ECG Electrodes Connection

ECG cable consists of two parts: main cable that is connected to the device and lead wires that are
connected to the patient
Use only one type of electrode on the same patient to avoid
variations in electrical voltages It is recommended to use silver/silver
chloride electrode. When dissimilar metals are used for different
electrodes, the electrodes may cause large offset potentials due to
polarization, which may be severe enough to prevent obtaining an
ECG trace. Using dissimilar metals may also increase recovery time
after defibrillation.
When you connect the cables and electrodes, make sure that no
metal part is in contact with the safety ground. Verify that all ECG
electrodes are correctly attached to the patient.
Interference from a non-grounded instrument near the patient
and/or ESU (Electrosurgical Unit) interference can cause inaccuracy
of ECG waveform.
Use only the manufacturer recommended ECG cable with internal
resistance. Other ECG cables and leads may cause improper
performance and/or provide inadequate protection during
defibrillation.
